OBJECTIVE Identify the incentive and constraint factors of artificial intelligence （AI） application in the pharmaceutical field， and promote the application of AI in the field of pharmacy. METHODS Based on the technology acceptance model （TAM）， technology-organization-environment （TOE） framework， and diffusion of innovation theory （DOI）， a TAM-TOE-DOI integrated framework was constructed through a four-stage research process of “theoretical review → dimension mapping → mechanism integration → proposition development”. Combining the analytical pathways of the above three theories in AI application in pharmacy with the integration mechanisms and core propositions of the TAM-TOE-DOI， literature review and deductive reasoning were employed to systematically identify the incentive and constraint factors of AI application in pharmacy from three levels：micro （TAM）， meso （TOE）， and macro （DOI）， and to propose optimization strategies. RESULTS & CONCLUSIONS At the micro level， the efficiency transformation and quality improvement brought by AI technology were the main incentive factors for perceived usefulness， while technological complexity and algorithmic opacity were the main constraint factors for perceived ease of use. At the meso level， the completeness of technological infrastructure， the strength of top management support and innovation climate， as well as external institutional pressure and competitive driving forces were the core incentive factors， whereas scarcity of organizational resources and talent shortage were the main constraint factors. At the macro level， relative advantage and observability were typical incentive factors， while technological complexity was a typical constraint factor. China’s health administration， medical insurance authorities， and other relevant departments should coordinate efforts at the macro， meso， and micro levels to advance AI application in pharmacy： optimizing human-computer interaction and implementing tiered training programs at the micro level； reinforcing organizational support systems and capacity building at the meso level； dismantling data barriers and building social trust at the macro level. Differentiated implementation pathways should be developed for medical institutions at different tiers.

Objective To analyze the core elements of standardized diagnosis of occupational carpal tunnel syndrome (OCTS). Methods Data of first reported OCTS case in Guangdong Province were retrospectively analyzed, including occupational exposure history, clinical manifestations, auxiliary examinations, and on-site occupational health investigation results. Furthermore, standardized diagnostic approaches for such occupational diseases were explored. Results The patient worked in a garment manufacturing enterprise, engaged in fabric cutting. The patient had a occupational history of at least three consecutive years of repetitive right wrist work, holding a 15.2 kg electric cutting tool for a cumulative 6.6 hours per day, with awkward wrist movements repeated 13 times per minute. Clinical symptoms included numbness and reduced muscle strength in the areas of median nerve distribution of the right hand, which were aggravated during work and relieved after rest. Physical examination showed inability of right hand to perform fine motor opposition movements of the thumb with the index, middle, and ring fingers; decreased tactile, pain, vibration, graphesthesia, and kinesthetic sensations below the right wrist; and positive Tinel′s sign over the median nerve at the wrist crease level, Phalen′s test, and reverse Phalen′s test of right wrist. Both wrist high-frequency color Doppler ultrasonography and nerve conduction studies and electromyography indicated damage to the right median nerve. However, only the findings from high-frequency color Doppler ultrasonography of the wrist meet the diagnostic criteria specified in GBZ 336-2025 Diagnostic Standard for Occupational Carpal Tunnel Syndrome. On-site occupational health investigation confirmed that the work involved typical repetitive wrist work, and three co-workers in similar positions exhibited comparable symptoms. The case was ultimately diagnosed as OCTS. Conclusion The definitive diagnosis of OCTS requires comprehensive evaluation of four core elements: a clear occupational exposure history, typical clinical symptoms and signs, characteristic objective examination findings, and quantitative on-site occupational health investigation data. Only when these four elements corroborate each other and non-occupational causative factors are excluded can a definitive diagnosis be made.

Occupational disease diagnostician (ODD) is the core technology professional who is responsible for occupational disease diagnosis and identification and the main inspection work for occupational medical examination. The implementation of regular assessment management for ODDs is a key component of standardized workforce management, which facilitates dynamic evaluation of professional competence, regulation of medical practice, and assurance of medical safety. Since January 2025, Guangdong Province has implemented regular assessment management for ODDs within its administrative region. The assessment adopts an integrated model consisting of three components including professional competency evaluation, performance appraisal, and professional ethics evaluation, with each assessment cycle lasting three years. ODDs who passed all three components are classified as qualified ODD, whereas those who failed to pass any one of the three components result in an unqualified assessment outcome. In the implementation of ODD regular assessment management, Guangdong Province has emphasized integrating assessment with quality evaluation, strengthening full-cycle supervision of ODDs′ professional conduct, optimizing assessment strategies for special groups of ODDs, and reinforcing the primary management responsibility of medical institutions. Meanwhile, ODDs′ professional competence, service quality, and professional integrity have been continuously promoted by adopting human-computer interactive assessments, information-based assessment management, and "elimination" mechanism.

This study analyzes the legal application of a dispute over employer identification in a case of occupational heat illness caused by part-time work to clarifying matters related to employer determination in occupational disease diagnosis using a case analysis method and factual reconstruction. The analysis is based on relevant civil laws and regulations, occupational disease diagnosis laws and regulations, and jurisprudential theories. The occupational disease diagnostic institution identified the part-time employer as responsible for the patient′s heat illness, which was both reasonable and lawful. This attribution safeguarded the rights of the worker, the primary employer, and the part-time entity. In occupational disease diagnosis, attention should be paid to de facto employment relationship, and the principle of "accountability lies with the actual employer at the time of the incident" should be followed to standardize employer identification. The health administrative department has supervisory responsibilities over occupational disease diagnoses. Workers′ compensation rights can be protected through the advance payment mechanism for work-related injury insurance. It is recommended to further improve internal procedures for occupational disease diagnosis, strengthen the dissemination of relevant laws and regulations and enhance the capabilities of occupational disease diagnosis physicians, to further protect workers' occupational health and their associated legal rights.

Objective To analyze the occupational health literacy (OHL) level and its influencing factors of workers in non-metallic mineral product industry in Yunfu City. Methods A total of 947 frontline workers from 24 non-metallic mineral products enterprises in Yunfu City were selected as the research subjects using the stratified random sampling method. The OHL level of the workers were assessed using the Occupational Health Literacy Questionnaire of National Key Populations. Results The overall OHL level of the research subjects was 58.3% (552/947). The OHL levels across four dimensions, from highest to lowest, were basic knowledge of occupational health protection (94.7%), healthy work practices and behaviors (81.8%), legal knowledge of occupational health (65.5%), and basic skills of occupational health protection (25.9%). The results of binary logistic regression analysis showed that workers with 2.0-<10.0 years and ≥10 years of work experience had higher OHL levels than those with <2.0 years of work experience (all P<0.01). Workers with a high school education or above had higher OHL levels than those with a junior high school education or below (all P<0.01). Workers in large- and medium-sized enterprises had higher OHL levels than those in small and micro-sized enterprises (both P<0.01). Conclusion The OHL levels of workers in Yunfu City's non-metallic mineral products industry can be further improved, particularly the occupational health protection skills and related legal knowledge. Workers with short seniority, low educational level, and in small and micro enterprises should be the key groups for improving OHL levels.

Objective To analyze a case of violations by an occupational medical examination (OME) institution and to explore the key control points for the supervision and management of OME institutions, as well as the core role of quality assessment in this context. Methods An OME institution suspected of illegal activities was used as the study subject. Retrospective analysis was conducted. Clues of suspected violations were identified by an on-site quality assessment. After investigation and verification by the local health authorities, legal action was taken against the institution for its violations. Results During an on-site quality assessment, the Guangdong Province OME quality control expert group discovered that the OME institution violated regulations, including unqualified personnel file, exceeding the scope of services category, issuing false reports, failing to report suspected occupational diseases on time, and failing to notify workers about suspected occupational diseases as required. The evidence was then submitted to the Guangdong Province OME Quality Control Center, which subsequently forwarded the case to local health administration department for filing and investigation. After the investigation, penalties were imposed on the OME institution for its illegal activities. Conclusion The key supervision and inspection points in the quality assessment of OME institutions include personnel file configuration, the quality control management system and its implementation, the quality of OME reports, and information reporting. Quality assessment plays a pivotal role in ensuring the legal and compliant practice of OME institutions, safeguarding the health rights and interests of workers, and enhancing the overall standard of the OME industry.

The pharmaceutical industry faces challenges in quality digitization for complex multi-stage processes, especially in small-sample systems. Here, an intelligent quality prediction and diagnostic (IQPD) framework was developed and applied to Tong Ren Tang's Niuhuang Qingxin Pills, utilizing four years of data collected from four production units, covering the entire process from raw materials to finished products. In this framework, a novel path-enhanced double ensemble quality prediction model (PeDGAT) is proposed, which combines a graph attention network and path information to encode inter-unit long-range and sequential dependencies. Additionally, the double ensemble strategy enhances model stability in small samples. Compared to global traditional models, PeDGAT achieves state-of-the-art results, with an average improvement of 13.18% and 87.67% in prediction accuracy and stability on three indicators. Additionally, a more in-depth diagnostic model leveraging grey correlation analysis and expert knowledge reduces reliance on large samples, offering a panoramic view of attribute relationships across units and improving process transparency. Finally, the IQPD framework integrates into a Human-Cyber-Physical system, enabling faster decision-making and real-time quality adjustments for Tong Ren Tang's Niuhuang Qingxin Pills, a product with annual sales exceeding 100 million CNY. This facilitates the transition from experience-driven to data-driven manufacturing.

Ribosome is an intracellular ribonucleoprotein particle that serves as the site of protein biosynthesis. Ribosomal dysfunction caused by mutations in genes encoding ribosomal proteins (RPs) and ribosome biogenesis factors (RBFs) can lead to a spectrum of diseases, collectively known as ribosomopathy. Phase separation is a thermodynamic process that produces multiple phases from a homogeneous mixture. The formation of membraneless organelles and intracellular structures, including ribosomes and nucleoli, cannot occur without the involvement of phase separation. Here, ribosome structure, biogenesis, and their relationship with ribosomopathy are systematically reviewed. The tissue specificity of ribosomopathy and the role of phase separation in ribosomopathy are particularly discussed, which may offer some clues for understanding the mechanisms of ribosomopathy. Then, some new ideas for the prevention, diagnosis, and treatment of ribosomopathy are provided.

Objective:To explore the clinical features and management of a child with Chitayat syndrome.Methods:A child presented at the Fengqing People′s Hospital on August 8 2019 was selected as the study subject. Clinical data of the child were retrospectively analyzed. Peripheral blood samples were collected from the child, father and sister. Whole-exome sequencing (WES) was carried out. Candidate variant was verified by Sanger sequencing. Genome Browser, AlphaFold, and PolyPhen-2 were employed for protein structure simulation and amino acid sequence conservation analysis. Pathogenicity of the variant was rated based on guidelines from the American College of Medical Genetics and Genomics (ACMG). Literature was retrieved from databases including CNKI, Wanfang, and PubMed using the keyword "Chitayat syndrome". The clinical characteristics and prognosis of patients with Chitayat syndrome were reviewed and analyzed. This study was approved by the Ethics Committee the Seventh Affiliated Hospital of Sun Yat-sen University (Ethics No.: KY-2024-086-01).Results:The child was born at full term and had special facial features, skeletal abnormalities, recurrent respiratory tract infections and global developmental delay. WES and Sanger sequencing revealed that she has harbored a heterozygous c. 266A>G p. (Tyr89Cys) variant of the ERF gene. Protein structure modeling suggested that the mutant protein has increased spatial distance between the side chain group and DNA, which may reduce its binding affinity to DNA. Amino acid sequence analysis indicated that the p. Tyr89 residue is highly conserved across multiple species. The variant was therefore classified as pathogenic (PM1+ PM2_Supporting+ PM6+ PS1+ PP3). The patient was diagnosed with "Chitayat syndrome". Nutritional support and rehabilitation training were recommended, though the child had died of severe pneumonia at 13 months old. Literature retrieval has collected 7 relevant articles, which involved 14 cases of Chitayat syndrome confirmed by genetic testing. Together with our case, all patients had facial dysmorphisms and skeletal deformities. Fourteen patients (93.3%) had respiratory distress. Seven of them (46.7%) had recurrent respiratory infections and 7 (46.7%) were confirmed with respiratory tract malacia. Eight (53.3%) patients had neuropsychological retardation, while 8 (53.3%) had growth delay. The main interventions for Chitayat syndrome include respiratory and nutritional support, and rehabilitation training for developmental delays. Conclusion:Chitayat syndrome is rarely seen and its clinical manifestations may vary. Airway management and early intervention of developmental delay are important for improving the prognosis.
